The cancellations also come as students nationwide, including in Massachusetts, planned walkouts to protest gun violence after 17 people were killed in a Florida high school shooting. In Revere, where schools are closed Wednesday, the superintendent said the walkout would take place at 10 a.m. at City Hall.

The student walk out in support of the Marjory Stoneman Douglas High School families and gun control as well as the student demonstration to support gun rights will begin tomorrow at 10 AM on the steps of City Hall.
